Guideway vehicle 99 of the present invention shown in Fig. 1.Guideway vehicle 99 comprises local top, downstream 100A and the covered upstream top 100B that opens wide.

Guideway vehicle 99 comprises the roof 102 (also being known as top cover) of conduction, this roof especially below top, the downstream 100A of guideway vehicle 99 and top, upstream 100B substantially on even keel extend.Roof 102 forms first electric conductor.Roof 102 is often used as the electrical grounding conductor.

Shown in Fig. 2 A, at top, downstream 100A, roof 102 comprises the roof structure 102A of an arch and the base plate 102B of a horizontal plate form, and base plate 102B is installed on the roof structure 102A.These two

parts

102A and 102B conduct electricity, and are electrical contact with each other.As previously mentioned, they are used as ground connection.

With reference to Fig. 1-3, guideway vehicle also comprises the pantograph 104 on the roof 102 that is arranged in downstream part 100A,, it is spacious that this place's roof 102 remains, that is and, quilt cover does not hide, and is as mentioned below.The bow 110 that pantograph 104 comprises fixed support 106, is installed in the hinge arrangement 108 on the support 106 and carried by hinge arrangement 108, bow 110 are used for contacting to give guideway vehicle 99 power supplies with the contact wire (not shown).Each parts 106,108 and 110, particularly support 106, formed second electric conductor, and in guideway vehicle operating particular moment, second electric conductor can have the voltage higher 5000 volts than roof 102, for example 12000 volts or 25000 volts.

Three insulators 112,114 and 116 remain on the roof 102 support 106.Each insulator 112,114,116 comprises one pile of insulation spacer, to avoid forming electric arc along these insulators between support 106 and roof 102.

Support 106 comprises

fastener

106A, 106B and insulator 112,114.These

fasteners

106A, 106B also conduct electricity, and have identical current potential with all the other positions of support 106.

Top, downstream 100A also comprises first insulating boot 118 that surrounds pantograph 104, thereby forms the housing of an open-top, also is known as " basin ", and pantograph 104 is set at this " basin " lining.

More properly, first insulating boot 118 comprises two bases 120,122 that project upwards from roof 102, each base 120,122 comprise towards pantograph, vertical inwall 124,126 substantially, and outer wall 128,130, outer wall 128,130 from the side 132,134 of guideway vehicle extends upward, up to engaging with corresponding inwall 124,126.Inwall 124,126 comprises parallel with the longitudinal direction of guideway vehicle substantially downstream part, and upstream portion, upstream portion and is joined with the upstream portion of the another side of pantograph 104 with respect to longitudinal direction at angle mutually, so that make the side of pantograph 104 and upstream besieged.Yet the downstream of pantograph 104 is still unlimited.In another unshowned embodiment, the downstream of pantograph also can be an osed top.

Each inwall 124,126 has ripple 136,138, and in the example shown, ripple is formed by the rib that extends downstream from the upstream on inwall, and described rib is followed on vertical mutually.Generally speaking, cross-sectional plane, particularly fin shape that ripple 136,138 can have Any shape, but it limits by two continuous flex points that change on curvature direction.At least 6 ribs preferably are provided.Selectively, ripple also can be formed by the groove that is positioned on

inwall

124 and 126.

As shown in the figure, first insulating boot 118 for example is preferably formed by mold pressing and is integral type.Especially,

ripple

136 and 138 is the single-piece part, that is, be integral with

inwall

124 and 126.

Selectively, first insulating boot 118 for example comprises by adhesion and/or machine riveting and fastening some parts mutually.For example, ripple is attached on inwall 124 and 126.Advantageously, in these embodiments, with respect to the assembly material of wall, the assembly material of ripple has better electric insulating quality.

Each inwall 124,126 extends near the support 106 of pantograph 104, with the size of reduction pantograph " basin " that extend betwixt.As a result, this mode near support makes and each have regional Z1, a Z2 on each inwall 124,126, and described zone is to 150 millimeters of the straight-line distance deficiencies of the support 106 fastener 106A and the 106B of support 106 (in the example shown, for).In the example shown, regional Z1 and Z2 are to 100 millimeters of the straight-line distance deficiencies of support 106 (as the distance " a " of figure).Z1, regional Z2 especially comprise separately from nearest some P1, the P2 of support 106 (in the example shown, being fastener 106A, 106B) in the zone.

Equally, each inwall 124,126 has regional Z ' 1, a Z ' 2 respectively, from 150 millimeters of the straight-line distance deficiencies of roof 102 (from 100 millimeters of the straight-line distance less thaies of base plate 102B, distance as shown in FIG. " a ").Therefore especially, inwall 124 contacts with roof 102 with 126, and regional Z ' 1, Z ' 2 comprise some P ' 1, the P ' 2 that contacts with roof 102 respectively, and this point becomes some Z ' 1, the Z ' 2 nearest apart from roof 102.

Point and the straight-line distance between the point among the regional Z ' 1 among the Z1 of zone are shorter.Particularly, between some P1 and the some P2 and some P ' 1 and the straight-line distance " d " put between the P ' 2 separately be approximately 50 to 100 millimeters (Fig. 2 B).

Yet, because the existence of ripple 136,138, the zone among the Z1 point and the point among the regional Z ' 1, regional Z2 in point and the point among the regional Z ' 2 respectively along the curve distance of inwall 124,126 with ripple 136,138 more than or equal to 400 millimeters, between preferred 400 to 800 millimeters, or between preferred 600 to 800 millimeters.Particularly, respectively between a P1 and some P2 and some P ' 1 with put distance " D " between the P ' 2 more than or equal to 400 millimeters (Fig. 2 B).

Therefore, although inwall 124,126 and to have the electric equipment of high potential difference between them very close, there is very little risk to produce electric arcs along inwall 124,126 between support 106 and roof 102.

Curve distance D preferably is 2 times apart from d at least, preferably apart from 3 times of d.And the existence of ripple 136,138 makes curve distance D is that 2 times or 3 times of straight-line distance d become possibility.In the example shown, inwall (not having ripple) is the plane, therefore can directly measure along inwall apart from d.

With reference to Fig. 1,4 and 5, top, upstream 100B also comprises roof 102, but does not comprise base plate in this position, and the roof structure 102A of an arch is only arranged.

With reference to Fig. 4, top, upstream 100B comprises first electrical equipment that is installed on the roof 102, or rather, is to be directly installed on the roof structure 102 of arch.In the example shown, electrical equipment is a circuit breaker 140.Circuit breaker 140 is connected with 148 with cable 146 with 152 via dish type shackle 150 respectively with 144 by joint 142.

Top, upstream 100B also comprises second insulating boot 154 that upwards arches upward from roof 102, second insulating boot comprises the insulation wall 156 that hides top, upstream 100B fully, particularly hide the electrical equipment that is positioned on the roof 102, for example circuit breaker 140 and cable 146,148.Insulation wall 156 is positioned at the top of the electrical equipment among the 100B of top, upstream with very short distance.

As shown in Figure 4, insulation wall 156 on the inboard 157 of roof 102, have ripple 158, to avoid between the low pressure point (particularly electrical grounding) of the high pressure spot and the electrical equipment of electrical equipment producing electric arcs along insulation wall 156.

Particularly, ripple be provided in insulation wall 156 from the distance of high pressure spot fully less than 100 millimeters, preferably less than 150 millimeters zone and insulation wall 156 from the distance of low pressure point fully less than 100 millimeters, extend between preferably less than 150 millimeters zone, the difference of potential between described high pressure spot and the low pressure point is 5000 volts or higher.

Therefore, with reference to Fig. 5, generally speaking, top, upstream 100B comprises first electrical equipment 161 of (for example ground connection) electric conductor 162 that has low pressure, and second electrical equipment 159, described second electrical equipment 159 is in the electric conductor 160 of high pressure (5000 volts or higher) when being included in electrical equipment 159 work.

Because insulation wall 156 is very near first and second electrical equipments, thus the regional U1 of insulation wall 156 from the distance of high-tension current conductor 160 less than 150 millimeters (distance among Fig. 5 " a ' ").Especially, regional U1 comprises from the nearest some X1 of high-tension current conductor 160.

The regional U2 of insulation wall 156 from the distance of low tension conductor 162 less than 150 millimeters (distance among Fig. 5 " a ' ").Especially, regional U2 comprises from the nearest some X2 of low tension conductor 162.

Yet the straight-line distance of a part of distance areas U2 of regional U1 is less than 100 millimeters, and vice versa.Particularly, the some X1 and the some X2 be separated by apart from d less than 400 millimeters.Therefore, the risk that produces electric arc along insulation wall 156 is arranged between the

electric conductor

160 and 162.

For fear of this risk, as shown in Figure 5, on the inside face of the insulation wall 156 between regional U1 and the regional U2, ripple 158 is set.The existence of these ripples 158 makes between regional U1 and the regional U2 curve distance along the insulation wall 156 with ripple 158 more than or equal to 400 millimeters, preferably between 400 to 800 millimeters.Especially, between some X1 and the some X2 along the distance D of insulation wall 156 greater than 400 millimeters.

With reference to Fig. 6, the manufacture method of top 100A of the present invention may further comprise the steps.

In step 200, except not being with ripple 136,138, other base the same with Fig. 1 to 3 is set at the desired location shown in Fig. 1 to 4.In this position, as previously mentioned, the inwall 124 of base and 126 and support 106 separate, and contact with roof 102.This step can be actually carried out by the rough sketch of for example making prototype or final products.This step also can be for example by computer simulation or calculating and by virtual execution.In the example shown, this step is finished by computer modeling.

In step 210, distance bracket 106 less than 100 millimeters, preferably less than 150 millimeters zone (regional Z1 and Z2) and apart from roof 102 less than 100 millimeters, preferably all be positioned at thus on

inwall

124 and 126 less than 150 millimeters zone (regional Z ' 1 and Z ' 2).(some P1 belongs to regional Z1 to first of the most close support 106 point on the

inwall

124 and 126, the point P2 belong to regional Z2) and inwall 124 and 126 on the most close roof 102 second point (some P ' 1 belong to regional Z ' 1, the some P ' 2 belong to regional Z ' 2) also in this step, be determined respectively.Equally, this step can be by actual or virtual execution.

In step 220, point on the Z1 of zone and the straight-line distance between the point on the Z2, point on the regional Z ' 1 and the straight-line distance between the point on the Z ' 2 are (that is, in an embodiment, inwall 124,126 along the plane), set with reference in the example shown 400 millimeters of predetermined values respectively.Especially, first P1,, the distance between P ' 1 and second P2, the P ' 2 sets with reference to described predetermined value.Preferably, described predetermined value is selected from standard.

Because it is very near apart from electrical equipment not have the inwall of ripple, original straight-line distance is also not all greater than predetermined value, therefore have along the breakdown risk of inwall, particularly be lower than under the situation of predetermined value at the straight-line distance " d " between some P1, some P ' 1 and some P2, some P ' 2.

In step 230, on the inwall between regional Z1 and the Z2 and between regional Z ' 1 and the Z ' 2 124,126, one or several ripple is set, thereby particularly, between a P1, P ' 1 and some P2, P ' 2, owing to be provided with ripple along inwall, so the distance between the point in these zones becomes more than or equal to predetermined value.Particularly, the curve distance " D " between some P1, some P ' 1 and some P2, the some P ' 2 is respectively more than or equal to 400 millimeters.

In step 240, in the present embodiment, make the inwall that has ripple.This step obtains

base

120 and 122, more at large, obtains actual inwall 124 and 126.In the example shown, this step comprises by the integral type mold pressing makes fairing 118 (as shown in Figure 3), and the

inwall

124 and 126 of fairing 118 has

ripple

136 and 138 respectively.

In step 250, by

base

120 and 122 being arranged on the desired location shown in Fig. 1 to 4, and, produce the top of guideway vehicle by

inwall

124 and 126 being arranged on desired location as shown in Figures 1 to 3.

Second fairing 154 is manufactured in a similar fashion.

With reference to Fig. 7, in step 300, insulation wall 156 ' being considered is used for forming the inwall 156 of second fairing 158, therefore, insulation wall is set at the desired location near first or second electric conductor, in this position, during the guideway vehicle operation, insulation wall has the difference of potential above 5000 volts.

In step 310, after insulation wall is set at the desired location, insulation wall 156 ' go up from the distance of the first high-tension current conductor less than 100 millimeters, preferably less than one or several zone of 150 millimeters, and from the distance of the second low tension conductor less than 100 millimeters, preferably less than one or several zone of 150 millimeters, just be determined.The result of this step as shown in Figure 8, first area (higher-pressure region) represents that with oblique straight shade line second area (meiobar) is represented with cross hatch.Fig. 5 shows regional U1 and U2.Thereby by be configured in the described zone determine insulation wall 156 ' on each point of the most close high pressure or low tension conductor.

In step 320, with reference to predetermined value T determine between first area and the second area along insulation wall 156 ' distance, be 400 millimeters in the example shown.As shown in Figure 8, the distance between first area and the second area is less than predetermined value T.

Therefore, in step 330, the insulation wall between first area and the second area 156 ' on be provided with ripple 158 ', so that between first area and the second area along the distance of insulation wall with ripple more than or equal to described predetermined value.The result of this step as shown in Figure 9.Especially, the distance on the insulation wall between the point of the most close high pressure or low tension conductor is more than or equal to 400 millimeters, preferably between 400 to 800 millimeters, or preferably between 600 to 800 millimeters.

Should be noted that step 300 can be actually carried out or for example by computer modeling and virtual execution to 330.

In step 340, by the insulation wall of so determining 156 ' and ripple 158 ' manufacturing have the insulation wall 156 of ripple 158.

At last, in step 350, make guideway vehicle 99 upstream top 100B by the desired location that the insulation wall 156 that will so make is arranged on shown in Fig. 1,4 and 5.

The present invention makes people near near the electrical equipment that is arranged on the guideway vehicle roof fairing is set.This fairing can limit a housing, this housing can finely hold the top such as the electrical equipment of pantograph or hide electrical equipment such as circuit breaker.

In addition, the present invention makes people can reduce distance between the electrical equipment, thereby possesses good compactedness.

More advantageously, fairing also has the trap door of maintenance usefulness, makes it to be easy near covered electrical equipment.These trap doors are positioned generally the place that is marked referring to figs. 1 through the numeral 400 in 3.Preferably, these trap doors form the window of using for inspection and maintenance by the transparent material manufacturing.

Therefore, the present invention makes people have electrical equipment fairing suitable shape, very close by setting, just can reduce the acoustics of aerodynamic turbulence and guideway vehicle, and need not to make the standoff distance between the electrical equipment excessive.
